Dr. Daniel Myran and Dr. Peter Tanuseputro publish two studies examining alcohol use and access to cannabis

Posted on Thursday, August 15, 2019

DFM graduate Dr. Daniel Myran and OHRI Researcher Dr. Peter Tanuseputro, who is cross-appointed to family medicine, have recently published two separate investigative studies in CMAJ and CMAJ OPEN relating to alcohol use in Ontario and access to cannabis following legalization across Canada.

Trends in emergency department visits attributable to alcohol use

The Montfort Hospital Emergency Entrance

In Rates of emergency department visits attributable to alcohol use in Ontario from 2003 to 2016: a retrospective population-level study, Dr. Myran and Dr. Tanuseputro, with co-authors Glenys Smith (OHRI) and Amy Hsu (BRI), examined temporal changes in emergency department visits attributable to alcohol use by sex, age and neighbourhood income. The study shows that the overall rate of emergency department visits directly related to alcohol use is rising in Ontario, at a rate significantly higher than the growth of all emergency department visits combined. While men and lower-income individuals are the most frequently admitted patients, the largest increases to rates of visits are in women and in particular young adults, who saw the largest increase (175%) in emergency department visits of any group. The study affirms the burden of alcohol use on our healthcare system, and identifies troubling trends based on age, sex and socioeconomic status that suggest a need to understand the factors that contribute to these observed increases, and inform healthcare providers and policy-makers.

Examining access to Canadian cannabis retail stores after legalization

Cannabis Culture in Saint Laurent, Montreal

Dr. Myran and Dr. Tanuseputro, with co-author (and DFM graduate) Dr. Catherine Brown, recently published Access to cannabis retail stores across Canada 6 months following legalization: a descriptive study. The study compares legally operating physical cannabis outlets (private, government-run and hybrid) in the first six months following the legalization of recreational cannabis across Canada, with a consideration of the dual goals of legalization: to replace the illicit market and restrict youth access. Results demonstrated that jurisdictions with a private/hybrid retail model had more stores, longer hours and were located closer to schools than those with a government-run model. Across Canada, all cannabis stores, regardless of retail model, are more likely to be located in lower-income neighborhoods than higher-income neighborhoods. Further research can help to determine whether these patterns relate to rates of harm from cannabis use, however, it is apparent that these trends warrant consideration from policy-makers and communities in effectively navigating cannabis legalization.
